Milwaukee OPEN-LOK 1-3/8" Carbide Teeth Multi-Material Multi-Tool Blade

The Milwaukee OPEN-LOK 1-3/8" Carbide Teeth Multi-Material Multi-Tool Blade is purpose-built for Milwaukee's OPEN-LOK oscillating tool platform, combining a 1-3/8" cutting profile with a carbide-tipped tooth pattern designed to move through multiple material types without a blade change. Professionals who transition between demolition, remodeling, and finish carpentry can rely on this blade to cut through mixed assemblies that combine wood, embedded fasteners, and other multi-material buildups. The OPEN-LOK interface is engineered for fast, tool-free blade installation and removal, helping crews stay productive by cutting downtime between passes and eliminating the need for separate wrenches or adapters. Whether the task is flush-cutting trim and molding, notching mixed-material assemblies, or working through nail-embedded lumber, this Milwaukee blade is sized and toothed to handle demanding, everyday oscillating multi-tool work on the jobsite.

  • Jobsite-Ready Design: Built to hold up to repeated use across remodeling, renovation, and mixed-material cutting tasks.

Milwaukee 49-25-1521 – Frequently Asked Questions

1) Will the Milwaukee 49-25-1521 blade fit my oscillating multi-tool, or only Milwaukee tools?
The 49-25-1521 uses Milwaukee's OPEN-LOK arbor interface, which mounts tool-free with no wrench or adapter. It is built for the OPEN-LOK platform, so a tool with an OPEN-LOK or OPEN-LOK compatible mount takes it directly. If your oscillating tool uses a different proprietary arbor, confirm it accepts OPEN-LOK before ordering.
2) Can this Milwaukee multi-tool blade cut through nail-embedded wood?
Yes. The carbide-tipped tooth pattern is what makes that possible, and cutting nail-embedded lumber and mixed assemblies with fasteners in them is one of its stated uses. A standard bi-metal wood blade will dull or lose teeth on buried nails; carbide teeth hold up.
3) How wide is the cut on the Milwaukee OPEN-LOK 49-25-1521 blade?
The cutting profile is 1-3/8 inches wide, which is the common width for general plunge and flush cuts with an oscillating tool. That width is wide enough to open up drywall or notch framing in one pass but still narrow enough to control in trim and molding work. If you need a tighter detail cut or a long straight kerf, a narrower or wider profile will serve better.
4) Is a carbide multi-tool blade worth it over a bi-metal blade for remodel demo?
On mixed assemblies, yes. Carbide teeth are the reason this blade can run through wood, embedded fasteners, and other buildups without a blade change, where bi-metal is really a wood-and-light-metal blade. For clean softwood cuts only, bi-metal is the cheaper consumable; for demolition and renovation work where you do not know what is inside the wall, the carbide blade stays in the tool longer.
5) What jobs is the Milwaukee 49-25-1521 multi-material blade actually used for?
Typical work: flush-cutting trim and molding, plunge cuts in drywall, notching mixed-material assemblies, cutting nail-embedded lumber, and opening access holes for plumbing, electrical, and HVAC runs. It is a remodel and renovation blade more than a finish-only blade.
6) Do I need a wrench to change the 49-25-1521 blade?
No. The OPEN-LOK mount is tool-free, so the blade comes on and off without a wrench or adapter. That matters if you are swapping between a cutting blade and a scraper repeatedly on the same opening.
7) What is the Milwaukee part number for the 1-3/8 inch OPEN-LOK carbide multi-material blade?
Milwaukee part number 49-25-1521, from the OPEN-LOK accessory series, 1-3/8 inch carbide-tooth multi-material blade. That is the number to quote when standardizing a crew's consumable list.
